One thing I’m finding with #watchOS10 is how much more useful the grid view of apps is. I used to find the grid view impossible to use, so I used the (alphabetic) list view of apps, with the dock for the few apps I would actually use regularly.
The dock has gone away in watchOS 10, but the new grid view is much easier to use, quicker to scroll through, and you can sort your frequently-used apps to the top, which makes it a good replacement for the dock.
